U4-3519 - ActiveDirectoryMembershipProvider not working

I can't get the ActiveDirectoryMembershipProvider to work with either the front end or back end.

Wired up as I used to in 4.7. I've even tried writing my own that overrides the ValidateUser method, with no luck.

In the back-end, once the provider gives a positive response to ValidateUser, the WebAPI service seems to respond with an 'object not set to an instance of an object' error. The JSON object returned by the API is: {"Message":"An error has occurred.","ExceptionMessage":"Object reference not set to an instance of an object.","ExceptionType":"System.NullReferenceException","StackTrace":" at lambda_method(Closure , Object , Object[] )\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass13.b__c(Object instance, Object[] methodParameters)\r\n at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)\r\n at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)"}

If I implement the provider for members, the back-end breaks with a similar error when entering the Members app. The stack trace for this is: at Umbraco.Web.Trees.LegacyTreeController..ctor(XmlTreeNode xmlTreeNode, String treeAlias, String currentSection, UrlHelper urlHelper) at Umbraco.Web.Trees.ApplicationTreeExtensions.TryGetRootNodeFromLegacyTree(ApplicationTree appTree, FormDataCollection formCollection, UrlHelper urlHelper, String currentSection) at Umbraco.Web.Trees.ApplicationTreeController.GetRootForMultipleAppTree(ApplicationTree configTree, FormDataCollection queryStrings) at Umbraco.Web.Trees.ApplicationTreeController.GetApplicationTrees(String application, String tree, FormDataCollection queryStrings) at lambda_method(Closure , Object , Object[] ) at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass13.b__c(Object instance, Object[] methodParameters) at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments) at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)

Thanks
